Molecular modeling characterization of cellulose and chitosan metal oxide hybrid interfaces

Abstract The interfacial electronic structure of biopolymer–metal oxide hybrids determine their stability, yet this structure is still not well understood. Here, we report a density functional theory study of 10 model systems consisting of cellulose and chitosan functionalized wi...

Multi-analytical characterization and radiation shielding assessment of natural ophiolitic rocks: a combined experimental, mineralogical, and simulation analysis

Abstract Ophiolitic suites derived from oceanic crust are rich in ferromagnesian and mafic minerals and exhibit relatively high densities, making them promising and economical materials for radiation shielding. This study evaluates ophiolitic rocks exposed along the Marsa Alam–Id...
